Application filed May 2, 1913. 'Serial No. 765,069. Y

provision of an automatically operating machine wherebyffobjects of metal such as brass mounts for beds and the like may be given a uniform satin finish in a most economical md cllicient manner. Requiring no manual attention other than the placing and reinovil oi' the Work pieces, the product of the machine is rendered uniformly excellent and independent of the varying skill .of diii'erent operatives, as ydistinguished from hand work. and the lcost of production is also reduced to a minimum.

lu order that the invention and the man ner of its use may be the more readily -understoml by those skilled in the art, I

have set forth in the accompanying drawings and in the following detailed description based -thereon a preferred embodiment of thc/invention, it being understood that such' drawings and` description are to be taken" as illustrative only and not in an unnecessarily limiting sense.

In these drawings, Figure 1 is a front4 elevation of a machine embodying the invention; Fig. 2 is an elevation showing the right hand end of themachine illustrated in Fig. 1;, Fig. 3 is an elevation showing the loft hand end of said machine; Fig. 4 is a detail sectional. view through the work holder driving member; Fig. 5 is, a fragmentary view of the abradant carrier; Fig.

. (l is a vertical longitudinal sectiony through the work holder; Fig. 7 is a vertical longi-v tudinal section through the main driving mechanism of the machine; and Fig. 8 is a side elevation of the work holding chuck removed from its mounting. H

In the embodiment of the invention shown and having particular reference to the drawings, the mach-ine comprises the frame-11 to which are secured as a substantially integral part by means of the clamping members l21 the vertical guides 13, 13 and a transverse member 14. at the topof the machine. /Upon the cross member 111 at the point ofY intersection between said member and the guides 13 are mounted peripherally grooved guide rollers 15, 15 and at an intermediate point upon the cross member 14 a pair of similar guide rollers 16, 16 is mounted, the last named rollers being :lournaled slightly out. of vertical ain-.ement as shown. r

Upon the machine frame and between :the guiding rollers, above described, are

adapted to be mounted alurality of machine units side by side. l `or the purposes of this description I have illustrated two units each a duplicate of the other and each comprising a reciprocating frame in thev form of a yoke, the side members 17, 17 of 'which are rigidly connected below Wlth the transverse I-beam 18,l which beam is guided for vertical reciprocating movement by sleeves 19, 19 sliding upon `the"` guides, 13' while the upper ortionsof the side members 17 are guided. letween the rollers 15,x 16.

The yoke frame is counter bailan"l d lby means of counter weights 20, 20 atta hed to cords- 21, 21 passing over sheaves 22,22.- Each of the yokes is provided in its lower portion with clips 23 and also above'with similar clips 24, one set secured to each of the `side members 17 by brackets 25, 25. To each of the clips are attached a plurality of strands26 ofV Wire or the like and to the other end ofA each ofsuch strands is ettachedga light lcontractile spring 27, While Y connecting the opposed ends of adjacent springs of each set are bundles of fibers of cord or the vlike 28, 28. These bundles of cords are adapted to be heavily impregnated with an abradent material'such as Tripoli composition, fine emery or other suitable material dependent u on the metal to be iinished and the articular finish to be given. In Fig. 1.of t edrawin I have indicated each 'of the bundles of ber with a single line, although in practice eiich .of said bundles is com osed of a. lar e number of fibers as indicate y in detail in l ig. 5.-

Each of the side members 17 of the yoke frames together with'its bracket 25, clips 24 and abradent lstrands 26 is so mounted in the machine asto be readily removed and ref placed. The lower ,end of each member isl direction by the rotation ot the confined .laterallyT between side aid rear stops LUSl while its brackets .25 hes depci ing lips which overlie one end oi a leal v Spring 181 secured in its mulial porlionon the beam 1S. The tension oit the npringg 18 presses the toe of the bracket 25 upward andV holds the upper end ol. the member l? yieldingly outward within the groove ot thel roller lVhen it is desired to remove one of the members 17 the upper end is pressed inward against the tension of the Sprino' le?" until it clears, the .roller .l5 in then s ung around the roller upon itu lower end as a fulernm and its lower brznlflfet .lifted from the spring .18h and jfree from the machine A new member will be inserted by an ob- Yions reversal of this o ieration..

In order to impar*y to the yoke frame a vertical reciiirocating motion as statedg and to reverse such movement at the upper and lower limits of traveh l. provide the lollowing described mechanism: Upon the drive-.shaft 29 is ixed a drive pulleyT l0 and upon the two sides ot the pulleyY are loosely mounted' drive pulleys Sl, 32,: flapted to be driven in opposite directions by usual belt cmmeetions.

The cam shaft 60 has mounted 'thereon drive pulley 6l loosely engaged by e slowly moving drive belt 02, the operative connec tion between the loosebelt 62 and Ithe drive pulley (Slis secured by means of a belt tightening device comprising a lever 63 carrying an idler pulley 64 in the plane of the belt und adapted to be brought into engagement with the same, while the opposite end ci' the lever is connected by means of a rod (SG with a treadle lever 07 having a toot piece 08 pro-- y jecting above the io'or in a position ccnvenient to the operator. It will be readily uni derstood that if the toot piece 08 is depressed the idler pulley 64 will lbe brought into enn gagement with the belt 62 to tension the same and thereby cause the driving ot the pulley 01 during such time only as such engagement is maintained. ln order to maintain the foot piece in depressed position l provide a trip rod 09 pivoted to the treadle lever 67 and provided with a lugr (0 havitutg` abeveled lower face and an abrupt upper tace edopted to engage below another lug 7l upon the machine treme, the trip lever 69 being yieldiugly drawn to the right by a suitably anchored spring 09a. ln, order to provide for the automatic stopping of the cam at the end of each complete revolution l mount upon the pulley Gl a stud 72, into the path of which projects the upper end of the trip lever 69. 'The engagement of the stud with the trip lever 69 serves to move the sume to the left, as shown in Fig. R7 releasing the engagement between the lugs 70 and l71 and permitting the idler ,pulley 0d to drop out of engagement with the belt 02 whereby the cem v59 is brought to rest with the Work holder occupyinga the inoperative posit-ion shown in Fig. l.

Tl lhld 'l l -l l'l "0 1e wort o er me unes a ciuc i iavmn a head 73 formed its e hollow casing w1tlnn Wluch reciprocates e wedge member 74, the inclined` faces 75 of which engage with pawls 7G pivoted at 77 causing the same, :is

'the Wedge member is moved in one direction,

to project radially through slots 78 of the head 73 while permitting the said pawls 76 to dropV Within said head when the wedge member is moved in the opposite direction. The heed is of ashape `adapted to lit within the work piece which is here shown as a.

mount 79', the outer fece of the pavvl 76 engagging the-inner walls of the mount and The vertical slotA 82 by means oi which the rod 80 ispermitted a limited movement upon each side of a pin 83 extending; transversely through the slot 82', the seid pin 83 being .tired in the huh 84C of a disk 85 'forming one member of e friction clutch by means ot' which the drive pulley 8G is connected and disconnected troni the work holding` clutch. .il spring 87 encircles the rod 7l bearing at one end upon the fixed member 88 and at the other end upon a shoulder 89 formed upon the rod Trl? whereby the rod is yieldingly pressed to the right as illustrated in Fig. 0. The rod 8O ext-ends beyond 'its bearing in the sleeve 8l, the projecting` end of the rod being in axial slincment with a shifting rod 90 slotted at 91 for movement upon a stud 92 and pivoted et 93 to a lever erm 94 which latter is pivoted at 95 to thc machine frame and has its free end connected at 96 with a suitably anchored spring 9'? and also connected at 98 with a cord 99 passing over the sheave 100 and attached at 101 to a tr'eadle lever 102 mounted beneath the machine and provided with a toot piece 103.

lltwill be seen that if the operator presses upon the foot piece 103, the lever 94 Will be swung to the left causing` the shifting rod 90 to ixnpinge against the end of the rod 90 and thereby move the same to the lett from the position shown in Fig. 6, compressing the spring 87 and permitting the pawls to bc retracted within ther head by the :lotion oi' the contractile springs 104 to release the mount. ,Concurrently the engagement of- 'the left handwall ofy the slot with the pin 83 due to the tension of the spring 87 is relieved and the eiigagement of the .opposite wall of the slot 82 with said pin causes the movement of the latter together with the disk 8:3 to the left against the tension of the spring 105 thereby relensing the engagement between the .friction surface 100 of the disk 85 and the con stantly driven pulley 8G whereby the rotation of the chuck ceases und the mount may 'be removed from the head 'i3 and another substituted. Thereupon when the operator having released the foot piece 103, the rods "Zeta and 80 are again moved to the right securing the mount upon the head and also clutching the friction disk to the drive pulley whereby the rotation of the clutch again ensues.

l? rom the foregoing it will be readily understood that (hiring one revolution of the slowly moving cam 59 the work piece will be swung by the work holder arm to one side into contact with the multiplicity of fibers charged with an abrading material and held in such position that substantially one-halt of the surface of the mount will be buried in' such bundle of fibers. While so held the yoke upon which the abradunt carrier fibers are strung; will be vertically reciprocatcd lio so to bring' the different portions of the libere successively i to contact with the work piece, which wil be rapidly' rotating with the heed of the work holder. After the cani has completed nearly one-halt of its revolution the work holder will swing in the opposite direction to bring the work piece `into the saine relation to the other abradant carrier upon the saine yoke and will there hold the rapidly rotating work piece half buried in the bundle otfibcrs on that side. At the completion ot' the second stage of the cam the work holder will be swung to the intermediate inoperative position illustrated in Fig'. l, and the Work piece or mount 'thus brought out of Contact with the Teciprocating` abradant carriers, whereupon the revolution of the cam 59 will cease by reason et the ei'igagement of the stop T2 with the trip lever (3f) andy the rotation of the clutch and the release of the Work piece will be effected by the operator stepping upon the foot piece 103. He will then remove the mount roin the chuck and. substitute another; immediately thereafter releasing the foot piece 103 and depressino the foot piece (38 in order to start the machine anew. The operator may then turn his attention to the next unit in the machine to remove the finished work piece from such. unit and substitute another' during the automatic imparting` of a satin finish to the mount held iii the first unit.
